Letters Patent No. 77,900, dated .May 12, 1868.

IMPROVEMENT IN OIL-SUIS FOR STEAM-PRESSURE.

TO ALL WHOM IT MAY CONCERN:

Bo it known that we, FRANKLIN P. MeCULLoN and WILLIAM WooncocK, both of the cityotr Philadelphia, and State of Pennsylvania, have invented a. new and improved Oil-Cup; and we do hereby declare that the following is a full, clear, and exactdescription of the same, reference. being had to the accompanying sheet of drawings, and to the lettersof reference marked thereon, making part of this specification, in which-- Figure 1 is an elevation.

Figure 2 a section of g. 1, and

Figure 3 a top viewf y i Similar letters refer to similar parts in the several views. v

A. is anv oil-cup, of the usual external appearance B is a. tapering plug or needle, which screws through the cap C. The end a of it takes into an opening, b, formed centrally in the swell D on the bottom of the cup. E is an index or finger, which is fixed to. the top of the plug B; it serves to indicate the amount of opening of the oil-channel bin the swell D, and being a spring, it keeps the plug from turning, by its point e taking into either of the centre marks al, which are arranged in an are of a. circle on the top of the cup C. F is a key, which takes into a corresponding opening formed diametricnlly through the nut or flange G of the cup. It is also for regulating the iiow of oil from thc cup to theparts to be lubricated, and to that end it has a h ole formed through it, corresponding to the channclsin the swell D and the screw-shank H. I is a spring-index or finger, on the end of the key; it is precisely similar in construction and operationv to the index E on the needle 13,'itsl point taking into either of a series of centre points, arranged in an arc of e circle on the surface of the cup.

Before filling the cup..with oil, the needle or tapering plugB is screwed down into the opening in the swell D, and the key F is turned to cut oil' all communication between the channels in the swell D end the screwsoeket I-I, after it has been filled, and it is intended to use either of the means of graduating the flow of oil; for instance, the needle B, then the key F, is set to permit e free, nninterrupt-cdiow' of oil, which is controlled by screwing the needle or plug either upor down, by rotating or moving the index-nger E, observing the point from which it started, to be able to see at aglance the degree of opening between the needle and the edge of the channel b. It' the key F is to be used apart from the needle, then the needle must be screwed vsufficiently high te permit a free ow of oil from the cup `into the channel b, and the index Iset et such apoint to graduato the opening in the key to pass the required quantity of oil, and the sieve K placed on the swell D, to filter the-` oil as it passes into the channel b. It is our intention to use both the needle B and the key' F', either together or separ-ately:

What we claim as our invention, and desire to secure by Letters Patent, is-

,1. The needle or plug B, and the index or finger E, in combination with an oil-cnp, A, substantially as shown.

2. The key F', finger I, sieve K, in combination with an oil-cup, A, substantially n-s shown. y

In testimony whereof, we hereunto sign our names to this specification in presence of two subscribing witnesses.
